Power system
8*5530Kw AC-Generators
which can supply the rig
with powerful manoeuvring
capability and enhances the
ability to meet both the
environmental conditions
and satisfies the high
operational workload.
Thruster system
8*4600kW Thrusters
equipped with an accurate
and reliable DP system,
which speeds up the reaction
time and will enhance the
ability to resist much
stronger wind.
Main diesel engine:
Wartsila Type 12V32,
5760KW
Thruster: Wartsila

The mooring system can obviously
save fuel when the water depth is 500-
1500m, which can be applied in deeper
water. As well, it can reduce the
operational costs and reduce the risk of
typhoons during typhoon season, so
we can secure it quickly and efficiently.

We have 3 intelligent operator chairs :
can be operated at the same time in driller’s cabin,
can make up stands off-line,
can greatly increase operational efficiency.

HYSY981 is the first 6th generation deepwater drilling unit
of CNOOC. The company has paid particular importance to
the operational team, it consists of the following 3 parts：
1, Excellent home employees from our other rigs
2, Recruitment of Expat key personnel
3, Recruitment of competent national employees

HYSY981 will recruit 14 Expat key personnel before June 2010,
include:
OIM: 2
Subsea supervisor: 2
Maintenance supervisor: 2
Tool pusher: 2
Senior DPO: 4
Senior E&I engineer: 2
The joining of Expat key personnel will bring us plenty of
operational and management experience, exchange of concepts and
knowledge, and will allow for better quality control during the
commissioning .

HYSY981 is an integrated, automated and highly
technically networked rig, so we have recruited several
experienced persons as instrument technician/software
engineers and network engineers. It will enhance the E&I
technician team experience on the rig and will increase the
maintenance ability for the equipment.

TTrraaiinniinngg ffoorr ssttaaffff
The team joined the rig building 2 years ahead of operations.
This has given us good opportunities to familiarize with the
rig and the chance to take training courses, such as internal
training, training from vendors, special courses for the main
equipments, and FAT training, etc.
